Removing PowerPath
Before Removing PowerPath
Before you remove PowerPath from the host:
❑Check the Powerlink website (http://powerlink.emc.com) for the most current information. We update the PowerPath release notes periodically and post them on the Powerlink website.
❑Stop any application and shut down any database that is using emcpower devices or a PowerPath Volume Manager volume. Unmount any file system mounted on a PowerPath Volume Manager volume.
❑If you are removing PowerPath from the host entirely (that is, you are not planning to reinstall PowerPath), remove all PowerPath Volume Manager volumes and volume groups allocated on the host:
Run the powervadm list command to determine whether any volumes and volume groups are allocated on the host. If volumes and volume groups are allocated, destroy them. Refer to Destroying a Volume and Destroying a Volume Group in the PowerPath for UNIX Volume Manager User’s Guide.
❑If you have a database partition, discontinue use of PowerPath devices as follows:
1.Stop the database manager.
2.Unmount PowerPath devices.
3.Edit the appropriate database configuration files so they no longer refer to emcpower devices.
❑If your PowerPath installation uses a storage system device as the boot device, remove PowerPath control over the boot device. Refer to Removing PowerPath Control Over a Boot Device on
